摘要

针对成形法铣齿加工弧齿锥齿轮大轮，对切削速度、切削深度、进给速度等切削用量对加工表面残余应力的影响规律进行了研究。根据成形法切削加工弧齿锥齿轮的特点，建立斜角切削有限元三维仿真模型，对齿轮的切削加工过程进行模拟分析，运用单因素法分别模拟了切削速度、进给速度、切削深度以及冷却液对工件表面残余应力的影响。由模拟仿真结果得知，弧齿锥齿轮斜角切削已加工表面残余应力沿层深呈“勺形”分布且表面为残余拉应力，亚表面为残余压应力，表面切向残余应力大于轴向残余应力；表面残余拉应力会随进给速度和切削速度的增大而增大，残余应力的层深随进给量的增大而加深，切削深度对残余应力的影响不明显；添加冷却液能够降低表面的残余拉应力。研究为弧齿锥齿轮切削加工残余应力分析提供了理论参考。

Abstract

In this study

milling large wheels for spiral bevel gears by the profile method

the effect of cutting speed

depth of cutting and feed rate on the residual stress on the machined surface is studied. According to the characteristics of spiral bevel gears machined by the forming method

a three-dimensional simulation model of bevel cutting is established to simulate the cutting process of gears

and the effects of cutting speed

feed rate

depth of cutting and coolant on the residual stresses on the surface of the workpiece are simulated using the single factor method. The simulation results show that the residual stresses on the machined surface of the spiral bevel gear are distributed in a "spoon" pattern along the depth of cut

the residual tensile stresses are on the surface

and the residual compressive stresses are on the sub-surface. The surface residual tensile stress increases with the increasing feed rate and cutting speed

the layer depth of residual stress deepens with the increasing feed

and the depth of cut has no significant effect on the residual stress. The addition of coolant reduces the residual tensile stress on the surface. Through this research

a theoretical reference is provided for the analysis of residual stresses in the cutting of spiral bevel gears.
